Dual 2-to-4 Line Decoder
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74VHCT139A is an advanced high speed CMOS 2 to 4
LINE DECODER/DEMULTIPLEXER fabricated with silicon
gate C2MOS technology.
TC74VHCT139AF
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The active low enable input can be used for gating or it can be
used as a data input for demultiplexing applications.
When the enable input is held High, all four outputs are fixed
at a high logic level independent of the other inputs.
The input voltage are compatible with TTL output voltage.
TC74VHCT139AFN
This device may be used as a level converter for interfacing 3.3
V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can
be applied to the input and output (Note) pins without regard to
the supply voltage. These structure prevents device destruction
due to mismatched supply and input/output voltages such as
battery back up, hot board insertion, etc.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
